LGA 2011
Intel's LGA 1366 (Socket B) in the high-end and performance desktop market areas[1]. This socket willLGA 2011,
also known as Socket R, is an unreleased Intel CPU socket. This socket is set to supersede
have 2011 protruding pins which touch contact points on the underside of the processor.
Socket 2011 uses QPI to connect the CPU to either additional CPUs in a dual socket system, or to add-in chipsets.
The CPU will handle northbridgefunctions, such as memory control, PCIe control, DMI, FDI, and other functions
integrated on chip.
This socket is expected to be released alongside Sandy Bridge-EX in Q3 2011, and will support 4 memory
channels as well as 40× PCIe 3.0 lanes;[2] the socket will measure 58.5mm x 51mm, and is backwards
compatible with LGA 1366 cooling solutions.[3]
Sandy Bridge
Sandy Bridge, formerly Gesher,[1] is the codename for the processor microarchitecture developed by Intel as the successor to Nehalem.
Based on the 32 nm process, development began in 2005 at Intel's Israel Development Center (IDC) in Haifa.
Processors based on this architecture are marketed as the second generation of Core i processors. Announced on January 3, 2011,
Mainstream processors were launched on January 9, 2011.[2]
On January 31, 2011, Intel announced that it had found a design flaw in its 6 series chipset named Cougar Point, that accompanies
the LGA 1155 socket, affecting SATA-II ports (number 2 to 5) and a recall was issued.[3] Intel announced that replacements will be
out to motherboard manufacturers by the end of February 2011. Due to pressure from OEM manufacturers, Intel brought forward the
scheduled date release of the revised chipset (B3) to begin shipping out on February 14, 2011. Most mainstream boards should meet
supply demand by the end of March 2011 to the beginning of April 2011.
